BACKGROUND: Meicillin-resistant Staphylococcus aureus(MRSA) is a common cause of nosocomial infections worldwide. Identification of strains by molecular typing facilitates epidemiological studies and improves disease control This study was performed to determine the usefulness of mecA-associated hypervariable region(HVR) polymerase chain reaction (PCR) and random amplified polymorphic DNA(RAPD) analysis in the investigation of a nosocomial MRSA infections. METHODS: Methicillin-resistance was identified by NCCLS disk diffusion method using the oxacillin disk. And PCR was done for detection of mecA gene. Antimicrobial susceptibility test, HVR-PCR and RAPD using 3 primers were performed for epidemiological analysis on isolates of MRSA. RESULTS: During the period from 1997 Dec. to 1998 May, 120 strains of S. aureus were isolated from clinical specimens. Among them, 78 strains were MRSA, and 72 strains were mecA positive. The strains of mecA positive MRSA were classified into four types by antibiogram, six genotypes by HVR-PCR, and 29 groups by RAPD using three primers. The combination of HVR genotypes and RAPD analysis showed 43 different types in 72 mecA positive MRSA isolates The five strains which were repeatedly isolated from the same patients showed the same HVR genotypes and RAPD analysis. CONCLUSIONS: Antibiogram, HVR-PCR, and RAPD could classify MRSA isolates into only 4-6 types, respectively, but combination of these methods could improve the typability. And combination of results of RAPD analysis using three primers were better than that using one primer in epidemiological studies of MRSA because of same reasons. It can be concluded that molecular typing of MRSA using HVR-PCR and RAPD assay is useful in epidemiolgical investigation of nosocomial infections caused by MRSA, because of its simplicity and reproducibility.

Bilateral diaphragmatic paralysis(BDP) is a rare disorder, which can be secondary to spinal cord injury, motor neuron disease, myopathy, noninfectious polyneuropathy, infection, iced saline cardioplegia performed during cardiac surgery, or idiopathic causes. there may be typical presentations such as dyspnea, paradoxical respiratory movement, and hypercapnic respiratory failure. It needs to exclude above secondary causes to consider idiopathic bilateral diaphragmatic paralysis. We report a 51-years-old man who presented with idiopathic bilateral diaphragmatic paralysis combined with acute pancreatitis. We couldnt, find out the association of these two clinical conditions. The patient was improved by mechanical ventilation.

PURPOSE: This study was conducted to analyze the change in the obesity index in girls receiving a gonadotropin-releasing hormone agonist (GnRHa), based on treatment duration, and to aid in nutritional counseling by investigating dietary habits and lifestyle. METHODS: Anthropometric examinations were conducted on 62 girls treated with GnRHa from January 2010 through July 2014. Parents were asked to fill out questionnaires on patient dietary habits and lifestyle. RESULTS: The group taking GnRHa for over 1 year had a higher rate of obesity increase than the group taking GnRHa for less than 1 year, but they had common habits related to obesity, which should be corrected. In addition, 69.2% of the normal weight group taking GnRHa for over 1 year gained weight, and needed more intensive programs, which include physical exercise and nutritional education. Although girls with precocious puberty showed a decrease in the intake of high-calorie foods with nutritional intervention regardless of treatment duration, they still had problems that needed improvement, such as shorter meals and lack of exercise. CONCLUSION: Girls with precocious puberty and their parents should emphasize maintenance of proper body weight, especially when treatment for over 1 year is anticipated. Consistent education in nutrition, ways to increase intensity and duration of physical activity, and the need to slow down mealtimes are important in managing obesity; doctors need to perform regular checkups and provide nutritional counseling.

The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.

OBJECTIVE: The Center for Epidemiological Studies Depression Scale (CES-D) is designed to measure the current level of depressive symptomatology in the general population. However, no review has examined whether the scale is reliable and valid among children and adolescents in Korea. The purpose of this study was to test whether the Korean form of the CES-D is valid in adolescents. METHODS: Data were obtained from 1,884 adolescents attending grades 1–3 in Korean middle schools. Reliability was evaluated by internal consistency (Cronbach’s alpha). Concurrent validity was evaluated by a correlation analysis between the CES-D and other scales. Construct validity was evaluated by exploratory factor and confirmatory factor analyses. RESULTS: The internal consistency coefficient for the entire group was 0.88. The CES-D was positively correlated with scales that measure negative psychological constructs, such as the State Anxiety Inventory for Children, the Korean Social Anxiety Scale for Children and Adolescents, and the Reynold Suicidal Ideation Questionnaire, but it was negatively correlated with scales that measure positive psychological constructs, such as the Korean version of the Rosenberg Self-Esteem Scale and the Connor-Davidson Resilience Scale-2. The CES-D was examined by three-dimensional exploratory factor analysis, and the three-factor structure of the scale explained 53.165% of the total variance. The variance explained by factor I was 24.836%, that explained by factor II was 15.988%, and that explained by factor III was 12.341%. The construct validity of the CES-D was tested by confirmatory factor analysis, and we applied the entire group’s data using a three-factor hierarchical model. The fit index showed a level similar to those of other countries’ adolescent samples. CONCLUSION: The CES-D has high internal consistency and addresses psychological constructs similar to those addressed by other scales. The CES-D showed a three-factor structure in an exploratory factor analysis. The present findings suggest that the CES-D is a useful and reliable tool for measuring depression in Korean adolescents.

PURPOSE: Cancer has become the major cause of deaths in Korea. Planning care for patients with terminal cancer is difticult. The prediction of length and prognostic factors of survival in the terminal cancer can facilitate the planning of a supportive care program aimed at patients need. The aim of this study was to identify length and those related factor of survival in the patients with terminal cancer. MATERIALS AND METHODS: This retrospective study was performed on 271 patients, who were diagnosed as terminal cancer in Seoul National University Hospital from March 1991 to February 1996. For getting the further informations about the patient, we interviewed with surviving relatives by telephone, and we requested administrative helps in order to take the informations about date of death. We examined the relations of 10 factors with survival in patients with terminal cancer. RESULTS: We could confirm 229 patients' death(84.5%) in 271 subjects. The median length of survival in patients with terminal cancer was 11 weeks(95%CI 10.0~14.0). By univariate analysis, history of surgery(p<0.01), performance(p<0.05), severity of pain(p <0.001), and dyspnea(p<0.05) were clinical factors in predicting survival. According to Cox's proportional hazard model including sex, age, history of surgery, performance, severity of pain, and dyspnea as variables, absence of surgery history(RR 1.398, 95%CI 1.038~1.882) and severity of pain(RR 1.398, 95%CI 1.044 ~1.872) showed independent prognostic value. CONCLUSION: The median survival was 11 weeks, and absence of surgery history and severity of pain were the independent prognostic factors for patients with terminal cancer.

The study was the clinical analysis of 509 patients with pure ocular injuries who visited to Chonnam University Hospital Emergency center from July 1, 1996 to June 30, 1997 retrospectively. Clinical data survey including sex and age distribution, causes of trauma, injury site, ocular disease, and surgical intervention was done. Most of ocular injury patients were male. 3rd and 4th decade who were socially active were nearly 50%. Direct and indirect injury from foreign body was the most common cause of ocular injuries followed by fist blow, traffic accident, falling down, and sport injury. Cornea was the most common ocular injury site (209 patients, 41.1%). The incidence of the traumatic ocular disease showed corneal erosion (117 patients, 22.9%) and then eyeball perforation, traumatic hyphema etc. by frequency of order. Eyeball perforation was the most common ocular injury which needed a emergency surgical intervention. As a results, emergency physicians have to pay attention to the cornea in case of any type of ocular injuries and eyeball perforation which caused by direct and indirect injury from foreign body.

PURPOSE: This study was undertaken to analyze the efficacy and sphincter preservation rate of platinum based neoadjuvant chemotherapy plus radiotherapy versus abdominoperineal resection and postoperative radiotherapy for anal cancer. MATERIALS AND METHODS: Data of forty-two patients with anal cancer were retrospectively analyzed. Among thirty-eight patients with epidermoid histology, four patients received radiotherapy, and nineteen patients received abdominoperineal resection and adjuvant radiotherapy with or without chemotherapy (APR+RT+/-CT), and fifteen patients received neoadjuvant chemotherapy and radiotherapy (CRT). The CRT regimen was composed of three cycles of 5-fluorouracil (1,000 mg/m2 bolus on D1-5) and cisplatin (60 mg/m2 bolus on D1) followed by 50.4 Gy to the tumor bed and regional lymphatics over 5.5 weeks. Both inguinal lymphatics were treated with an identical dose schedule. Residual disease was treated with an additional three cycles of identical adjuvant chemotherapy. An identical dose schedule was used for post-operative radiotherapy. Median follow-up period was eighty-five months. RESULTS: Overall five-year survival rates were 80.3%, 88.9 and 79.4% for entire patients, APR+RT+/-CT group, and the CRT group, respectively. No significant difference was found between the two groups (p= 0.49). Anus preservation rate for the CRT group was 86.7%. Age (p=0.0164) and performance status (p= 0.0007) were found to be significant prognostic factors by univariate analysis. Age (p=0.0426), performance status (p=0.0068), and inguinal lymph node metastasis (p=0.0093) were statistically significant prognostic factors by multivariate analysis. No case of RTOG grade 3 complication or higher was reported. CONCLUSION: This and other recent studies have shown that combined chemotherapy plus radiotherapy for anal cancer results in a high rate of anal sphincter preservation as well as local control and survival. Furthermore, neoadjuvant use of chemotherapy with a cisplatin based regimen rather than a concurrent regimen may lead to a decrease in complications.
